To ALL'PERSONS To WHOM THESE PRESENTS MAY OOME:

Be it known that I, NEWIEL `J. WILLIS, of Boston, in the county of Suffolk, and State'of Massachusetts, have invented an Improved Spring-Bed Bottom; and I dol hereby declare the same to be fully described inthe following specification, andrepresented in the accompanying drawings, of which i Figure 1 is al top View, and E liigure 2 a longitudinal sectiou of the said bed-bottom.

.In 'such drawings, A A.' are two cylindrical wooden bars, .extending transversely across a rectangular frame, B, they being arranged near the ends of such frame. Each of such hars serves to support aV series of looped springs, C' C C, te., composed Ofwires, bent in the form, and arranged with respect'to thebars A A, in manner' as represented. Resting on these springs is a series of slats, D D D, 8m., each of such slats being placed on two of `the springs, and provided with two notches or grooves, a a, extending across it, for reception of the .middle straight portions of the two springs.` l l l In further carrying out my invention', I combine 'witlreach ofthe slats, and arrange with respect to it and the-two springs, in manner as shown in tig. 2, two turn-buttons, 6,6, each of such buttons being held to the slat vby a screw or rivet, c, so that the button may he revolved on such connection. By turning these buttons ici-oss the notches aa, the slat will'beprcvented from becoming disengaged from its springs, either bydownward pressure or by any sudden elevation of the Slat tending to throw it entirely aho've either spring. By turning the buttonsoll` the springs, the slat may be readily lifted from them. The turn-buttons also serve to keep the slats and their springs in union when the bedstead-framcfis turned up on either ofits sides or ends. Each spring, by being fastened at or near its extremities to the round bar A, will, while boing depressed, be supported by the spring. Y A

In my invention or spring-bed bottom, as described in the -United States patent, dated February 27,1866, and numbered 52,937, I make use of a strap to each spring, snoh'strnp going along the upper surface thereof.

This strap is an inconvenient application Oitthe slat to the spring, and is liable to'several objections which my present invention completely obviates.

of springs C, (o as described.
